BOX.

Application filed June 30, 1923. Serial No. 648,?33.

This invention relates to boxes,'and more particularly to wirebound and similar boxes for shipping` purposes.

Among other objects the invention is intended to provide a box of lightand strong construction, and one susceptible of' certain advantages in manufacture.

An illustrative box containingl an embodiment of' the invention is shown in the annexed drawings, in which:

Fig. 1 is a perspective view of the unassembled box parts'in position about to be assembled,

Fig. 2 is an end elevation of the box showing the lid in open position,

Fig. 3 is a perspective view of the completed box in condition for shipment of contents.

The illustrative box comprises a wireboundblank folded about end sections or heads.

A rectangular form of box being illustrated, the foldable blank for forming the successive box sides, other than the ends, comprises in this instance four sections 1, 2, 3 and 4. These sections' consist of suitable side material, such for instance as wood veneer, attached toend cleats 5, 6, 7 and 8, respectively; and the several sections are flexibly united in cooperative foldable relationship by the binding wires 14k, certain of which wires are stapled through the side material to the cleats. ln this instance the cleats are shown having mating ends of the Well-known mortise and tenen type.

Then the blank is folded into box form around the heads 9 and 10, and the continuity of the binding` wires .is completed by'tying or fastening` their extremities, as indicated at 13, the cleats of the respective sections cooperate in the usual manner to form approximately rigid cleat frames at the opposite sides-or heacs of the-box. spaced apart and held by the side material and bound by the wire binding and resisting the tension of said binding, as well understood in the art. Y

By constructing the blank so as to fold with adjacent portions of adjacent side material overlapping` one another, on the prin ciple explained in the reissued patent to Inwood and Lavenberg No. 12,725 of November 26, 1907, the binding wires become tensioned in the folding operation over the dihedral corners of the box, thereby increasing the-strength and promoting the tendency ofthe box toresume its shape after undergoing distorting strains, as for instance when the box is dropped on a trihedral corner.

For strength and lightness of construe-- tion, the end sections or heads 9 and 10 of the box consist of sheets of thin rigiditying material, such as sheet metal, which combine the advantages of stiffness and nonfrangibility with capacity for flexing under strains and of bending under such severe strains as would disrupt ordinary Wooden headed boxes.

These heads are shown having upper flanged ends 11 and correspondingly flanged lower ends 12, formed by bending the ends of the heads at right angles to their body portions. Said flanged ends 11 and 12 provide angle reinforcement at the top and bottom of the box, and serve as attaching flanges for securing the heads to the top and bottom cleats.' It will be observed that the heads are so disposed that their opposite side margins bear against the inner faces of the corresponding cleats 6 and 8, while the' flanges 12 overlie the bottom cleats 7 and the flanges 11 underlie the top or lid cleats 5, both flanges 11 and 12 extending between the ver ical cleats 6 and 8. It will be appreciated that when the heads are so arranged with relation to' the cleat frames of the box, the upper and lower ends of the head 9 may be readily7 secured to the top and bottom cleats from the exterior of the box, thereby contributing to the rigidity of the box. f

' Viewing the end ofthe completed box as shown in Fig. 3, the structure of the end section or head 9 and the arrangement of its top and bottom flanges 11 and 12 with relation to the cleats of theocleat frame, produces the effect of a girder extending between vertical cleats 6 and 8, said flanges 11 and 12 forming thetop and bottom chords of the girder to brace their contiguous cleats and increase their resistance to distorting strains. This construction is effective in opposing c ushing forces as well as diagonal effect, and Vtor increasing` resistance ot the heads to distorting forces, the heads may be suitably corrugated or provided with stamped ribs to form braces, struts or the like, one appropriate t'orm ot head tor a box ot the illustrative ill'orm being shown, providing stilieniug ribs In assembling the illustrative box (which may be :turnished to shippers as an unt-folded shook) the sections 2. 3 and it ot the foldable blank maybe folded about corresponding sides ot' the sheet metal heads 9 and l0, and the heads may be secured to the cleats 6 and 8 ot the sections 2 and lf by nails or other appropriate fasteners driven trom the interior ot the bom ivhile the bottom flanges l2 of the heads may then be secured by such tastenings to the bottom cleats 7. After the box is lilled, andV after the top section or lid l is closed and secured by complet-ing the continuity ot the Wire bindings around the box, the top lianges ll oit the heads may be secured in the same manner to the top or lid cleats 5.

Thus the filled and closed box, in condition tor shipment of contents, has all ot its cleated sections, including the lid, firmly tied together by the heads of the box as ivell as by the binding` wires, and the opposite heads tied together at all sides by cleated sections. Which contributes to the strength and rigidity ot the package and prevents any bowing or separation of the box sides at unsecured margins, with accompanying` exposure and bulging' contents. Moreover the construction of the vsheet metal heads with top and bottom flanges and the securement ot these flanges to the top and bottom cleats by astenings driven in a plane transversely of that ot the tastenings of the side margins ot the heads to the cleats 6 and 8, further increases the rigidity ot the box and its resistance to distorting strains.

The illustrative box is a comparatively7 deep narrow box adapted tor shipment of such articles as cans of motor lubricating oil; and the construction described is admirably adapted to provide a strong and eicient box of this type. Furthermore the bottom flanges ot the sheet metal heads provide convenient means 'for attachment ot the heads to the bottom cleats.y to which it would be ordinarily somewhat inconvenient to secure the heads by tastenings driven trom the interior in such a deep narrow box. Thus the illustrative box typilies a construction having sheet metal heads appropriately flanged to provide angle reinforcement*suitable to the form and dimensions ot the box7 and for attachment ot the heads to such ot the cleats as could not be conveniently secured by tastenings driven trom the inside, in this instance the top and bottom cleats.

The girder-like sheet metal box heads further contribute an element oit elasticity lo the box, and cooperate with the vvire bindings in liexibly resisting distorting strains and tending to restore the box to its original shape a'tter reliet 'from such strains. For instance. it the box should be dropped upon a trihedral cornea or subjected to diagcual strain.` the eleated sides ot the box may llcx or shi'lt relatively to one another., with accompanying tlexure ot the binding` uires and the metal ends ot' the box; while the tension ol' the binding Wires and the resiliency ot the heads will cooperate in rxsisting such flexing and in restoring the box to its original form after the strain is relieved.

Boxes ot the construction described may be manufactured with somewhat smaller dimensions than ordinary Wooden headed `wirebound boxes, Without sacrificing the capacity et' the box. In other Words, bv virtue ot the thin material employed tor the heads. boxes of specified'interior dimensions may be made with shorter sections ot material tor the toldable eleated sides ot the box. This materially contributes to lightness of construction and results in a considerable saving of material in the manufacture ot such boxeson a large commercial scale.I and an appreciable gain is made in the storage oit such boxes in large quantities. Furthermore, such boxes possess unusual strength and rigidity, combined with an unusually great elastic limit, promoting the capability ot the box to endure rough usage.

It will be obvious that the present invention is not limited to the speciiic details ol construction of the illustrative box, since the same may be variously modified to suit the different forms and dimensions o't boxes required for various shipping purposes.

Having described an: embodiment ot my invention, I claim:

A vvirebound box ot deep and narrou7 lorm comprising, in combination, sheet metal heads having top and bottom flanges; and a toldable cleated blank folded about said heads; the vertical margins oit said heads abutting against and being secured to the vertical cleats ot the blank bv tastenings driven from the interior ot the box: and the top and bottom flanges ot said heads being secured to the top and bottom cleats of the box by astenings driven from the exterior` said flanges ext-ending substantially the full distance between the vertical cleats.

In testimony whereof. l have signed my name to this specitieation.

JEFFERSON CAYLOR.
